lorasvet [3.4K]

Answer:

8,229,437 cents

Step-by-step explanation:

Using the compound interest formula;

A = P(1+r)^n

Given

Principal invested = $37700

rate r = 5% = 0.05

Time t = 16years

Substitute into the formula

A = 37700(1+0.05)^16

A = 37700(1.05)^16

A = 37700(2.1829)

A = 82,294.37

Hence the amount of money, to the nearest cent, in the account after 16 years is 8,229,437 cents
